New CRC Technical Report - Climate Variability Program
December 04, 2003
CRC Technical Report 03/12 ' Stochastic Generation of Climate Data' by Ratnasingham Srikanthan and Senlin Zhou has now been published.
One of the goals of the Climate Variability Program in the CRC for Catchment Hydrology is to provide water managers and researchers with computer programs to generate stochastic climate data. The stochastic data are needed at time scales from less than one hour to a year and for point sites to large catchments like the Murrumbidgee and Fitzroy.
The first technical report in this series, 'Stochastic Generation of Climate data: A Review (CRC Technical Report 00/16), reviewed methods of stochastic generation of climate data and recommended the testing of a number of techniques. The second technical report, 'Stochastic Generation of Annual Rainfall Data' (CRC Technical Report 02/06), compared the first order autoregressive and hidden state Markov models for the generation of annual rainfall data. The third technical report, 'Stochastic Generation of Monthly Rainfall Data' (CRC Technical Report 02/08), evaluated the modified method of fragments and a nonparametric model for the generation of monthly rainfall data. The fourth technical report, 'Evaluation of Two Rainfall Data Generation Models' (CRC Technical Report 02/14), evaluated the transition probability matrix model with Boughton's adjustment for interannual variability and the simplified daily and monthly mixed model for the generation of daily rainfall data.
This report describes stochastic climate data generation models for the generation of annual, monthly and daily climate data (rainfall, potential evapotranspiration, maximum temperature and other variables) that preserves the correlation between the different variables. The performance of the model are evaluated using climate data from ten sites located in various parts of Australia.
